IMPROVEMENT IN DEODORlZlNG-COMMODES.

Specification forming part of Letters Patent N 0. 222,1 33, dated December 2, 1879 application filed March 12, 1879.

To all whom it may concern Be it known that I, DUNCAN G. HARTMAN, of the city of Baltimore and State of Maryland, have invented a new and useful Deodorizing-Oommode, of which the following is a In the accompanying drawings, Figure 1 is a top view with the cover raised. Fig. 2 is atop view as seen with the seat and water-proof pad removed. Fig. 3 is avertical section of the apparatus with the metal cover. on. Fig.

4 is a top view when the metal top is on."

The subject-matter hereinafter claimed will its mode of operation explained. i i l The letter A represents a metallic cylinder which forms theou'terlcasing of the commode. This case hasa. tight bottom,"c, of any suitable material; but for a stationary commode fire-brick is deemed preferable.

B is a removable perforated bottom, which is supported by suitable legs upon the tight bottom, leaving a space between the two.

O is a metallic cylindrical receptacle for the solid parts of the excrement, and is of a size to fit Within the outer casing and leave all around an intervening space, cl. This receptacle is provided with a bottom, the central part of which is perforated or provided with a grate, e, and is sustained by feet f above the perforated bottom B, leaving a space between, and the receptacle may be removed bodily at any time. A l

g A urine-pipe, D, is vertically secured in the bottom ofthe inner receptacle, and its end projects below the bottom, and connects with a pipe, 1), which, in a stationary commode,

' connects with a larger pipe, E, the upper end of which enters the sideof the outer casing, and the lowerend leads to the cellar or a pit in the yard, and if to the cellar may terminate over a box or barrel containing ashes or dry earth, in such manner as to for air to have entrance.

The upper end of the urine-pipe is provided with a funnel, F, located just below and at the front of the seat, and is detachable from the pipe. y 7

On the inner side ofthe edge of the outer leave an opening part of the bottom of the receptacle are cov-,

ered temporarily, so as to be water-tight, by means of a water-proof pad, 2', of size to completely cover the openings, and consists of paper, cotton, or felt saturated with pitch, tar, wax,'or melted rosin, and around the edge made to adhere to the bottom by some of the same material applied in a plastic state. This pad, thus constructed and applied, serves the double purpose of first sealing the grating in the bot; tom, to prevent excrement from passing into the space below, and subsequently serves, by reason of its combustible nature, as a kindler, as hereinafter described. 1

A vertical pipe, J, is secured in the space between the two cylinders, its upper end ter? minating just below the seat and its lower end below the removable perforated bottom B. The purpose of this pipe is to facilitate the introduction of any combustible material-such as dead-oil--and also to apply a fuse or a fireball.

L is a horizontal tube through the outer case, and enters the space below the bottom B, its object being for the introduction of fire when the excrement is to be consumed, and it serves also as a draft-opening.

N represents a metallic cover adapted to fit close and entirely over the top of the outer case. This cover is provided with a mica slide,

K, which closes a hole so located as to come directly over the upper end of the tube J. A pipe or flue, P, for ventilation, allowing the escape of odor and gases and the products of combustion, enters the side of the outer case, near the top, and connects with a chimney-flue of the house.

To prevent the hinged cover h from becom ing soiled by contact of gases or moisture, a detachable-covering, R, is secured over the seat-hole or 'on the cover in any convenient manner. This covering may be in the form of a sack capable of containing a limited quantity of deodorizing and absorbing material in by charcoal.

- a powdered state, such as peat charcoal; or

this cover may be of such material as to per- Init of saturating it with some liquid disinfectant or deodorizer which is also of an inflammable character. In the present instance it is shown attached to-the cover; but, as stated, it

may be secured over the seat-hole.

The seat G and the close-fitting cover N are not both in position at the same time, but are used alternately, each for itsspecial purpose.

The manner of using my commode may be described as follows: The perforated bottom B is first placed within the outer casin g, and a quantity of pulverized charcoal or other absorbent combustible material is placed on and under the bottom in such manner as to leave spaces for air-draft. The receptacle C- is then placed over the bottom B, care being when that the grating or perforations are properly covered by the water-proof pad. The bottom of the receptacle and the pad are then covered Upon using the commode one of the coverings, R, is detached and dropped into the receptacle, and another is placed in position.

Upon the accumulation of excremental matter in quantity sufficient to make it desirable or necessary to get rid of the same, it may be consumed by fire,to effect which the seat G is removed and the metallic cover N is substituted. A small quantity of dead-oil or equivalent material may now be poured through the hole in the cover into the pipe J, by which it is delivered below the bottom B. A small ball of cotton-waste or other suitable material saturated with-the dead-oil is ignited and then dropped down the pipe, which sets fire to the oil and combustible material in the bottom spaces. The heat soon melts the rosin or material, that causes the pad t to adhere, and the flames of the fire thus kindled pass upward through the grate or perforations, the tube L and pipe E affording the requisite supply of air, while the flue P carries oi the gases and products of combustion. It will thus be seen every necessary provision is made in my commode for converting it into a furnace whereby to consume the excrement.

If desired, the fire may be introd need through the'horizontal pipe L by means of a gasoline fire-pot or blow-pipe, such as used for heating soldering-irons.

For the sick who may be unable to leave the bed, a water-tight sack containing some combustible absorbing material, such as mentioned above, may be used, and the sack and contents thrown into the receptacle and consumed. I

' I do not, however, here claim a sack for this purpose, reserving the same for another application for a patent.

. Having described my invention, I claim and desire to secure by Letters Patent of the United States 1.
